The-invention relates to an improved suction and exhaust fan for drawing, gathering, picking up, moving, conveying and discharging material of a long fibrous nature, such as paper, rags, cotton, grass, hay, straw, wood fibre, pieces of rope and the like.

The usual suction and exhaust fan will pick up materials of a fibrous nature, but no fan heretofore Will convey and discharge such materials, owing to the materials wrapping around the hub and arms and blades of the fan and preventing discharge from the fan housing, so that the fan is immediately choked, clogged and stopped from operation.

A suction and exhaust fan that will convey and discharge long fibrous materials is very advantageous for removing by suction the paper wrappers from tomatoes, grape fruit, oranges and the like, and for picking up and conveying and discharging grass, hay, straw, cotton, wood fibre, long fibrous silo and many like and similar substances.

The present invention has provided an improved suction and exhaust fan that by partial vacuum commonly termed suction, removes the wrapping papers from fruit and vegetables, such as oranges, grape fruit, tomatoes and the like, and picks up and conveys and discharges grass, hay, straw, long fibrous silo, long wood fibre, pieces of rope,

and many like and similar substances.

With these and other objects in view, the invention consists in the features of con struction, functions performed, combinations and arrangements of parts as hereinafter set forth and more particularly pointed out in the appended claims, the accompanying drawings illustrating a form of the improved suction and exhaust fan which has been built and which performs perfectly as described.

In the drawings Fig. 1 is a section of the improved suction and exhaust fan on line 1-1 of Fig. 2.

Fig. 2 is a view in elevation of the suction and intake side of the fan.

Fig. 3 is a fragmentary section on the line 83 of Fig. 6.

Fig. 4 is a flat View of the deflector forming part of the improved fan.

Fig. 5 is a sectional view on line 5-5 of Fig. 3.

Fig. 6 is a view of the improved fan broken ofl to save room in illustrating and broken open to show the interior construction.

The frame 1, bearings 2, shaft 3, hub 4, arms 5,- blades 6, closed side housing plate 7, housing closing plate 8, suction side housing plate 9, corner connecting angle shaped bars 10, periphery housing closing plate 11, suction pipe 12 and exhaust pipe 13 are all of common and well known form and construction.

The suction pipe connecting sleeve 14 is connected at 15 t0 the suction pipe 12 and forms a section and part of the suction pipe, which is disposed outwardly from the housing plate 9 and in the opposite direction from the fan hub 4; The end 16 of the sleeve 14 is provided with the radially disposed flange l'Tand is connected to the housing plate-9 by the rivets 18; the sleeve is also provided with the integral member 19 which forms apart of the support of the fan.

The deflecting plate 20 is preferably as shown a segmental disk with a spherical shape formed therein, the plate presenting a concaved face in the direction of the suction pipe 12 and a convex shape or face in the direction of the fan comprising the hub l, arms 5' and blades 6.

The apex of the spherical shape of the deflecting plate 20 extends a considerable distance within the housing plate 9 in the direction of the fan hub 4 and between the blades 6 and the plate forms an elbow extension of the suction pipe 12' opening within the housing in the direction of the exhaust side of the fan.

The rivets 21 secure the deflecting plate 20 to the housing plate 9 as shown in full lines of Fig. 3 and the holes 22 are provided in the plate for the purpose of retarding the position of the plate with reference to the rotation of the blades 6 to the position indicated by dotted lines 23, while the holes 25% are proided to advance the deflector plate in the direction of rotation of the blades to the position indicated by the dotted line 25.

For the usual forms-of fibrous material the deflector plate 20 is employed approximately in the position shown in full lines of Fig. 3 and for short fibrous material the plate may be retarded to the position indicated by the dotted lines 24, while for extremely long fibrous material the plate is preferably advanced to the position indi cated by thedotted line 25.

The object and function of the deflecting plate 20 is to deflect the suction and all matter including fibrous -materials 'contained therein and therewith away from the hub 4 and arms 5 and sufiiciently away from the blades 6 to prevent the fibrous material from wrapping around the blades and arms and the hub of the fan), i c 7 V I The shaft 3 and fan'comprising hub 4, arms 5 and blades 6 are rotated in the direction indicated by the arrow 26 of Fig. 2 and a whether itbe atmosphere, vapor, smoke or gases, the suction is drawn by the blades 6 through the suction pipe-12 and sleeve 14 andinto the housing comprising plates 7, 8, 9 and 10 and deflected away fromthe hub 4,

, armsf 5 and away from the blades 6 as the blades rotate away from the exhaust pipe 13 by the deflectingplate 20 and are direct ed toward and into the exhaust pipe, and all imental' spherical shaped deflecting plate spread across the opening of said suction pipe to said housing and forming an elbow extension of said suction pipe and opening in the direction of the exhaust side of said fan.

straw, long fibrous silo, wood fibre, pieces of rope and the like are carried with the atmosphere, vapor, smoke, gas and the like and exhausted through the exhaust pipe 18 to any predetermined and desired place the exhaust may lead to. v The deflector platedirects the fibrous material from the hub 4 and spokes 5 and the I blades 6 at the point where it would wrap around the hub, spokes and blades were it not for the directing deflection of the deflector plate.

:The improved suction and exhaust fan is V of particular importance for removing paper wrappers from fruit and vegetables, as orange s, grape fruit and the like, and for removing, conveying and discharging hay,

straw, seed stocks and the like and can be advantageously employed for picking up,

conveying and discharging all kinds of'short and long fibrous materials that can be picked up by a suction fan. 7

Having described my invention, what I claim as new and desire to secure by Letters Patent, is 1. In a suction andexhaust fan, a fan housing, a fan-within said housing and mounted on a shaft protrudingthrough one side of 7 said housing, a suction pipe connected to and opening into the opposite side of said housing, an exhaust'pipe connected to and leading y from the periphery of said housing, asegmental spherical shaped deflecting plate spread across the opening of'said suction pipe with the concaved side of saidplate facing the suction pipe and the apex of the spherical
